You can easily import a model built with ERwin into PowerDesigner with no loss of metadata. PowerDesigner allows complete flexibility through reliable linking and synchronization between conceptual, physical and object-oriented model approaches, providing outstanding model clarity and flexibility.
ERwin v3.x (.erx)
ERwin v4.x (.xml)
ERwin v7.x, v8.x, v9.x (.xml) – the ERwin model must be saved as Standard XML Format, and you must uncheck Only save minimum amount of information in the ERwin Save as XML File dialog box.
An ERwin logical model can be imported into either a PowerDesigner conceptual or logical model (CDM or LDM), while an ERwin Physical Model is imported into a PowerDesigner physical data model (PDM).

While PowerDesigner can import all your object display preferences and will retain color and font information, it does not support multiple colors for columns in a single table. The default column color will be used during the import.
